UNiKA SPT-3RT Stage Series Phase Tester
SPT-3rt is the best tools of UNiKA Stage Series. This tool is suitable for any speaker manufacturer, touring and fixed installation applications. It can be used for testing phase either the speaker or balance cable. An external microphone input socket can be connected external dynamic microphone to test the speakers that have been hung up. By using neodymium magnet to combine transmitter and receiver units for easy carrying.
Features
- Detect the phase accuracy in any audio system, prevent the musical signal from cancellation due to the opposite phase.
- Detect the XLR signal cable to prevent it from contact fail, brokerage or opposite connection.
- Built-in external microphone input socket in order to use for the harder environment such as the hanging speaker cluster.
- Testable range from 10 cm to 3 meters. An ideal environment can be tested far away from the axis of speaker for 7 meters.
